Question

Wings of bird and bat are
A.Homologous with no analogy
B.Analogous with no homology
C.Neither homologous or analogous
D.Both homologous and analogous

Answer 1

Hint: The analogous and homologous organs are evidence of evolution. The analogous organs have different structures performing similar functions while homologous organs are similar structures performing different functions.

Complete answer:
The analogous organs are the organs having distinctive structures which are known to perform similar functions. This can be due to different precursors present in similar conditions and need to perform the same functions. The homologous structures are known to share a very much comparable embryonic beginning; the analogous organs are known to have very similar functions. For illustration, the bones present in the front flipper of a whale are found to be homologous to the bones present in the human arm. These are not analogous structures. Butterfly wings and the bird wings are found to be analogous but not homologous. The wings present in birds and bats are closely connected and serve similar functions. Genetically, the wings of bat and bird are known to have exceptionally little in common; the final common ancestor of bats and birds did not have wings like either bats or birds.

The homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function.

Hence, the correct answer is option (B)

Note: Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
